Luminic Light Meter

Built for film shooters. Spot metering, exposure compensation, and a reading log that saves every shot with a thumbnail. Accurate to within 1/3 stop.

The light meter your film camera is missing. Point your iPhone at the scene, press MEASURE, set your camera. Accurate to within 1/3 stop, tested against professional meters.

Luminic looks and works like the handheld meters of the 80s and 90s: a real LCD, real stops, no clutter. Built by a film shooter, for film shooters.

METERING • Aperture priority: set your f-stop, get the shutter speed. • Shutter priority: set your speed, get the f-stop. • Scroll through equivalent exposure pairs to pick the combination you want. • Spot metering for reading just the highlight or shadow that matters. • Exposure compensation to shift the reading before you measure.

READING LOG Stop scribbling exposures in a notebook. Flip the LOG switch and every reading is saved with aperture, shutter, ISO, timestamp, and a thumbnail of the scene. Long-press LOG to review your session. Up to 50 readings, stored only on your phone.

ACCURACY • Full ISO range from 3 to 8000, in real 1/3 stops. • Calibration trim to match your own camera's meter, up to 2 EV in either direction. • A REC indicator and a confirmation tick tell you every reading landed.
